Yes they do make a smaller speed up pulley, before you go that route are you sure that the engine is running up to speed?
Here is some information that I have on pulleys. It's been a long time since I messed with them and I do not remember where I got this information. Check before you buy something.
Small drive pulley (44" and 50" decks) is as follows
IH 126393-C1 44A decks with serial number 81742 and above. (Small pulley)
all other decks (44, 50, 50A) list IH 59703-C3(some list C-2 as well) as correct. Including a note about 44" decks below serial # 81741. (large pulley)
NOTE: These numbers are only good for YELLOW tractors. The 5/8" belt on the 82 series requires a different pulley.
